Police are investigating racist death threats made against Chelsea coach Avram Grant. The club?s training ground in Cobham, Surrey, was sealed off after a member of staff opened a package containing a letter and a quantity of white powder. The note said the powder was lethal and specialist police and fire teams raced to the scene yesterday.

Surrey police said today that tests revealed the powder was harmless but officers are believed to have given advice on security to Israeli Grant, 52, and his wife Tzofit, 43, who have two children.

One note read: "?You are a back-stabbing Jewish b*****d. When you open this letter you will die a very slow and painful death." A second message made sexual threats against his wife, adding: "Then she will die."
